Application filed September 29, 1926. Serial No. 413,568.

To ({ZZ whom it may concern:

Be it known that I, ALEXANDER Twnnocowsnl, a citizen of the UnitedStates, residing at Detroit, county of "Wayne, and State of Michigan,and I, STANISLAW KLosiNsKi, a citizen of the United States, residing atDetroit, county of Wayne, and State of Michigan, have invented certainnew and useful Improvements in Rotary Heels, of which the following is aspecification.

This invention relates to improvements in foot wear and particularly toimprovements in the heels for boots and shoes.

It is the principal object of the invention to provide a heel-plate orplug which. is readily attachable to or removable from an ordinary heeland which is held thereon interchangeably and against displacement.

A further object of the invention is the provision of a heel-plate whichcan be locked in its adjusted position and which may be turned in orderto present a new wearing edge to the ground, if for instance it is wornoff faster at one side than the other, and which can be locked in thisposition.

A still further object of the invention is the provision of a heel-platewhich can be lowered somewhat or within certain limits in its entirety,if the general wear of the heel should this require, and which may belocked in any of its positions.

These and other like objects are attained by the novel construction andcombination of parts hereinafter more fully described and so forth inthe appended claims.

In the accompanying drawing forming a material part of this disclosure-Figure 1 is a fragmentary side view showing a conventional type of shoewith the heel-plate according to the present invention attached thereto.

Fig. 2 is a top plan view of the heel-plate taken along line 2-2 of Fig.1.

Fig. 3 is a section along line 3-3 of Fig. 2.

Fig. 1 is a rear end vlew of the heel-plate.

Fig. 5 is a bottom viewof the heel-plate seen in the direction of thearrow, Fig. 4.

Referring in detail to the drawing, a shoe of the conventional type hasa heel part 11 and a sole 12, as customary. The heel.

part may be composed of a number of the usual lifts.

To this heel part 11 a heel-plate, generally indicated at 13, isattached by means of screws or the like 14 preferably 6 in number (Fig.3).. This plate 13 has an upstanding marginal flange 15 and within thespace or area limited by this flange at the front part of the heel, achamber, 15 is provided which is filled by a rubber cushion 16 ofpeculiar formation, as indicated in Fig. 5, which is held within theplate by any desired means for instance a cement or the like, and thelower face of which is flush with the bottom face of the plate.

The rear part of the heel-plate is formed by a solid body 1? integrallvmade with the metal of the plate and provided with a centralscrew-threaded opening 18 for the reception of the threaded outer faceof the stem 19 of a plate 20 to which is secured by means of screws 21or the like a rubber cushion 22 of circular configuration which on itsunderside shows a circular or central depression 23 provided with acentral opening 24: through which the bit of a screwdriver or similartool may be introduced. The upper part of the stem 19 carries a metallicspider 25, as shown in Fig. 2,which is provided'in its outerperiphery'with recesses 26, while between two ridges 27 and 28 to bothsides of itsjcenter, a bore -or hole 29 is arranged for the reception ofa screw, the head of which is located within the hollow space of thestem 19, so that itcan be en gaged by the bit of a screw-driver etc.introduced through the opening 24: and the opening 32 in the center ofthe plate 20.

Any of the recesses 26 is adapted to be engaged by the inner end of alocking member 33, the outer end of which is passed through the cushion16 and the flange 15 at its rear face and carries a pin or the likemanipulating member 3%. Between the inner wall of the cushion 16, andthe outer wall of the stem 19 a spring 35 is wound or coiled around themember 33.

When in use,the heel-plate 13 is attached to the heel by means of thescrews 14. preferably 6 in number and the plug 22 with its plate 20 andstem 19 is secured in its place within the opening 18 by means of ascrew driver, while the end of the locking member 33 engages one of therecesses 26. If

the plug or cushion 22 has become worn more on one side, than on theother, it may be turned by a screw-driver introduced through 24 afterthe locking member 33 has been withdrawn out of its engagement with oneof the recesses 26. The recesses 26 are deep enough, to allow the entireplug or cushion 22, when worn off to be lowered and locked in itslowered position by means of the locking member 33 without the danger oflosing the entire cushion. 7

Having thus described our invention, what we claim as new and desire tosecure by Let ters Patent of the United States is 1. In a deviceof thecharacter described, a heel-plate adapted to be secured to a shoe heel,and having an annular central cavity in its rear body and a rubbercushion in its chambered front part, a metallic plate hav: ing a stemscrewed into said cavity, a rubber cushion secured to said metallicplate, a recessed spider at the upper end of said stem, and meansengaging inthe recess of said spider for locking the parts in theirrelative adjusted positions.

2. In a device of the character described, a heel-plate adapted to besecured to a shoe heel, an upstanding marginal flange on said I plate, achamber formed in the front end of said plate, a rubber cushion securedin said chamber, a solid body forming the rear part of saidfplate andhaving an annular central cavity formed by screw-threaded walls, ametallic plate having a screw threaded stern secured in said cavity, arubber cushion having a central depression and a central opening securedto said plate, a spider on said stem provided with marginal recesses,means for securing said spider to a shoe heel, and means engaging therecesses in said spider for locking the parts in their relative adjustedpositions.

3. In a device of the character described, a heel-plate adapted to besecured with its upper face to the heel of an article of foot wear, andan upstanding marginal flange on said plate, a chamber limited by saidflange formed in the front part 01" said plate, a solid rubber cushionsecured in said chamber, a solid body formed with the rear part of saidplate and having an annular central bore provided with screw-threadedwalls, a metallic plate having a central opening and a hollow screwthreaded stein adapted to be threaded into the bore of said solid body,a circular rubber cushion adapted to be secured to the underside of saidmetallic plate, and having a central depression and a central hole inalinement with the opening 01 said metallic plate, a spider formed atthe top of said stern having a plurality of mai ginal recesses, twocentral ridges formed with said spider, and a central opening adapted toreceive a screw formed in the middle of the spider between said ridges,a locking member engaging with its inner end any of the recesses of saidspider and passed through the cushion and the rear flange, an operatingring at the extreme outer end of said member, and a spring coiled aroundsaid member between said cushion and said stem for normally locking theparts against displacement in their relative adjusted posi tions.

In testimony whereof we have afiixed our signatures.
